PDN Optimization: Balancing Performance and Cost in SoC Designs
October 22, 2025 | Zach Caprai. Siemens EDAEstimated reading time: Less than a minute
The evolution of adaptive system-on-chip (SoC) devices has brought unprecedented computing capabilities to modern electronic systems. However, with this advancement comes increasingly complex power delivery challenges. In particular, as organizations strive to accelerate time-to-market while managing costs, optimizing power delivery networks (PDNs) has become a critical factor in successful product development.
This article demonstrates advanced PDN optimization techniques through a real-world case study of AMD’s Versal adaptive SoC platform. Using the VCK190 evaluation kit featuring the Versal AI Core series VC1902 device, I’ll explore how effective PDN design and optimization can help meet demanding technical specifications while addressing essential business goals.
Understanding Modern PDN Challenges
Modern SoCs require precise power delivery across a broad frequency spectrum, from DC to the gigahertz range. The PDN must maintain stable voltage levels while managing current transients and minimizing impedance across all frequencies. For configurable devices like the AMD Versal adaptive SoC, this challenge is particularly complex because power requirements vary significantly based on device configuration and application.

Single Pair Ethernet (SPE): A Valuable Option for Modern Designs
04/20/2026 | Marcy LaRont, I-Connect007When it comes to designing PCBs and full systems for increasingly complex electronics hardware, who doesn’t want to reduce complexity and cost? Single-Pair Ethernet (SPE) has emerged as a solution and is gaining rapid attention across industrial electronics and PCB design because it enables Ethernet communication over a single twisted pair, replacing the traditional two- or four-pair cabling used in standard Ethernet networks. This seemingly simple shift has significant implications for designers: smaller connectors, reduced cable weight, longer reach, and the ability to carry both data and power over a single pair.
Webinar Review, Part 2: Building the AI Backbone at IBM on Systems-level Packaging
04/20/2026 | Marcy LaRont, I-Connect007The second presentation in a recent Global Electronics Association’s Executive Pulse webinar series widened the lens on advanced packaging, moving beyond the component level to a systems-level view of how AI is reshaping the electronics landscape. Building on Dr. Hemanth Dhavaleswarupu of AMD’s previous discussion of chip-level packaging innovation, Dr. Jung Yoon of IBM explored the broader infrastructure implications, from the data center floor to the global supply chain.
